is I R w I 3% as M izing device 1, a superheater 2, and an air mixing chamber 3. The vaporizer is shown in detail in Figures 4 and 5, and consists of an outer chamber 4 to which is connected a pipe 5 at the upper end thereof, and also a pipe 6 at the lower end thereof. The exhaust gases pass into this pipe 5and are.

utilized in heating the vaporizer. Located centrally of this outer chamber 4 is a compartment 7 having integral radiating vanes 8. This compartment 7 is rigidly serured to the upper and lower walls of the outer chamber 4 and may be formedintegral there- 1. with. Extending between the side wall 9 of the outer chamber and the side wall 10 of the compartment 7 is a baffle plate 11. There is a similar bathe plate 12 on the other side of the outer chamber. These baffle plates are so located that the exhaust gases passing in through the pipe 5 will be led in and about the radiating vanes on to the opposite side of the compartment 7 then back on to the near side thereof, and finally across and out through the pipe 6.

'Located in this inner compartment 7f'is an inner chamber 13 which is the vaporizing chamber for the oil. This chamber 13 is provided with a supporting flange 14 which rests on the upper end of the compartment 7. The chamber 13 and flange 14 are secured to the members forming the compartment 7 by a cap plate 15 through which suitable bolts 16, 16 pass, whichbolts are threaded into the members of the compartment 7. The oil to be vaporized is led through a pipe 17 which extends through the cap plate 15, and is thus delivered to the inner chamber 13. The inner chamber is slightly spaced from the inner wall of the compartment 7 so as to insure its easy removal from the com partment 7 The oil passinginto this inner" chamber 13 will come in contact with the hot w'alls thereof, and will bethoroughly vaporized. The vaporized oil will pass out through theopening 15 in the wall of the inner chamber 13, thence into a pipe 19 which extends from the wall of the compartment 7, and also through the outer wall of the outer chamber 4. It is noted that this inner compartment 7 which is provided with radiating vanes, extends entirely across the outer chamber 4 so that the exhaust gases are compelled to cross from one side of said outer chamber to the other as above mentioned. This vaporizer as clearly shown in Fig. 1 is attached to the head of the engine cylinder whichis indicated at 20. Also attached to the cylinder head 20 is a .super-.

heater 2, which superheater consists of an inner cup-shaped member 21 having a flange 22. The side of the cylinder head is formed with an opening as clearly shown in Fig. 2, through which this cup-shaped member is inserted, and said member is secured to the cylinder by a cap plate 23 and suitable bolts 24, 24. Located in this cup-shaped member 21 is a'partition 25 which extends the full height of the cup-shaped member but terminates short of the inner end thereof. The pipe 19 is attached to this cap plate 23 so that the vaporized oil passes through the cap plate and along one side of the partition 25, and then across to the other side thereof and out through a pipe 26. This pipe 26 1S connected by suitable devices to an air mixing chamber 3. The air mixing chamber-is provided with an air inlet port 28 cap 33 attached to the valve stem. The suction of the engine will open the valve 29 and draw air into the air mixing chamber. The bracket 30, of course,'is provided with suitable ports to allow the air to'enter and pass through the valve. The lower wall .34 of the air mixing chamber is inclined and extends substantially across the lower portion of the air. mixing chamber, leaving'only a comparatively small air intake passage 35. This inclined plate or wall 34 collects the heavy oil vapor condensing in the air chamber, and causes the same to accumulate at the lower end thereof and to pass through an opening 36. into a collecting chamber 37. This condensate collecting in the chamber 37 is led through a pipe 38 to the supply tank with which the pipe '17 is connected.

A check valve 39 is preferably provided in the pipe 38 so as to prevent the oil from being drawn from the supply chamber directly into the mixing chamber. This air mixing chamber, 27 is connected to a cylindrical valve casing 40, which valve casing is in turn connected to the head of the cylinder at 41. This valve casing is, in a sense, the intake manifold for the cylinder of the engine. There is also ap'ipe 42 connected to this valve casing 40. Located in the valve casing is a rotatable valve 43 which canbe turned by means of a suitable handle 44. The pipe 42 leads to a gasoline or light hydrocarbon oil carburetor diagrammatically indicated at 45. When the valve is set as shown in Fig. 3, then the engine can be run on gasoline. This is for the purpose of the easy starting of the engine. As scorn however, as

' the engine is Well under way, then'the valve 1 can be turned so that the suction of the engine will draw-from theair mixing chamberl' This will cause the superheated vaporized oil to be thoroughly mixed with th'e air taken in through the air valve, and the mixed gas thusformed led to the engine cylinder.

While I have shown the superheater as located in the head of the engine cylinder, it

will be understood, of course, that it may be otherwise located and heated. The essential feature, however, is the locating of the superheater between the vaporizer and the air mixe ing chamber. While I have shown the vaporized in the absence of air, and means for a mixing air with the superheater vaporized oil and directing the same to the engine cylinder. y

In testimony whereof, I aflix my signature.

porizer as heated by the exhaust'gases passing from the engine, it will be understood also that this vaporizer for the heavy oil may be otherwise'heated.

It is to be understood'that the term va porizer as used throughout the description 7 V and claims, is used in its broadest sense to cover an exploslve fuel generator, whether the fuel be in the form of vapor or gas. The

same is true of the expression vaporized oil. The invention is directed broadly to V the changing of the hydrocarbon oils into a vapor or gas by the aid of "heat.

While I prefer to use my improved fuel generating device a in connection with hydrocarbon oils heavier than gasoline, it will be understood that it may also be used with gasoline or other lightor hydrocarbon oils, and will be very effective, e,

for the reason that the use of the heat will more efliciently vaporize or gasify the oil passing therethrough.

It is obvious that minor changes in the de- I tails of construction and the arrangement of theparts may be made without departing I from t-he'spirit of theinventionas set forth in the appended claims.

Having thus described the invention, what I claim'as new and desire to secure by Letters Patent, is

- 1. A charge forming devicefor'hydrocan bon engines including in combination, a vaporizing chamber, means for supplying hydrocarbon'oil to said chamber, means for utioil and directing the same to the engine cyllizing the exhaust gases from said engine for vaporizing the oil in said chamber, a 'superv heater closed to the atmosphere'projecting intothecombustion chamber, means for passing the vaporized oil from the vaporizing 'chamberthrough said superheater whereby said vaporized oil is superheated and further vaporized in the absence of air, and means for mixing air with the superheated vaporized inder.

2. A charge forming device for hydrocar-- bon engines comprising a vaporizing chamher, means for conducting the exhaust gases from the engine about said vaporizing cham- 7 her whereby the walls thereof are heated,

means for directing a jet of hydrocarbon oil into andagainst the walls of said vaporizing
